What Fitness Watch Is Right for You? Apple Watch, Garmin, Fitbit or Whoop?
Fitness wearables are no longer just step counters. Today’s devices track heart health, sleep quality, recovery, stress and training performance - but not all fitness watches are built for the same type of user.
The quick verdict
Choose an Apple Watch if you use an iPhone and want a full smartwatch with strong health and safety features. Pick Garmin for serious training, outdoor sports and long battery life, Fitbit for simple everyday health and excellent sleep tracking, and Whoop if you want deep recovery and strain insights from a screen-free band you wear around the clock.
